Are there any specific file permission settings (chmod) that should be applied to a .txt file used for storing links in PHP to enhance security?

When storing sensitive information like links in a .txt file in PHP, it's important to apply appropriate file permission settings to enhance security. To restrict access to the file, you can set the chmod value to 600, which allows only the owner to read and write to the file. This prevents unauthorized users from accessing or modifying the link data stored in the file. 

// Set file permission settings for the links.txt file
$filename = 'links.txt';
chmod($filename, 0600);
